<p>PROBLEM TO BE SOLVED: To enable change in the sizes of packing materials so as to be brought into agreement with the size of a product to be packed and make the used packing materials reusable by combining frame materials which have joining faces on a plurality of their faces and are freely extensible and retractable in their longitudinal directions, in packing materials for packing a product such as a refrigerator and an ice making machine. SOLUTION: Packing materials 1 have angle materials 2... forming frame materials made of metal such as steel or of resin such as plastic and having an L-shaped sectional shape, and a plurality of mounting holes 3 are bored in each angle material 2 so that two angle materials 2 are joined to each other with screws 4 by utilizing any of the mounting holes 3. That is, when the angle materials 2 are joined to each other, the length thereof is made adjustable to a predetermined length by selecting positions of the mounting holes 3 through which the screws 4 should be inserted. Four angle materials 2 in a vertical direction, eight angle materials 2 in a lateral direction on upper and lower sides, and eight angle materials 2 in an oblique direction are used, and respective faces are joined together with the screws 4, thereby packing a product.</p> |
